So, I bought 500mls of Nic back around Christmas time from one of the big sales. It didn't occour to me at the time to freeze it, so I just stashed it all in my vaping amoire. (Yes, I have an amoire dedicated to vaping, mostly just DIY stuff)
When it first arrived, it was clear and perhaps even very slightly amber in color. Taste was fine to my tastebuds. Arrived in plastic pour-spout bottles.
Fast forward to yesterday. I've mixed up all but 60mls of it, and as I was examining the nic, I noticed that the coloring was off. It's now the color of a medium scotch, a medium tan if you will. It smells fine, I didn't taste anything off with it.
Is this normal? Some sort of oxidation from the liquid sitting at room temperature?
Thanks for your time,-
